The monograph presents the results of theoretical and experimental studies of non-stationary processes of modification of metal surfaces by electric current, by switching it with a liquid-electrolyte electrode. This process is called plasma electrolyte treatment (PET). On the basis of the research carried out, complex hardening technologies and equipment have been created. Technologies allow oxidizing, alloying and changing the structure of local areas of the surface of products, which greatly...
Topics: Electrolytic dissociation, electrical breakdown, plasma, heat treatment, surface modification,...

The book contains data on development of the technologies based on the use of non-stationary electric discharges in plasma jets. Formation of a plasma jet takes place under the effect of non-stationary detonation waves propagating between electrode units. In this case the energy parameters of the plasma can be controlled by a fuel mixture composition, electric potential and geometric characteristics of a device. As a result of interaction with plasma, the treated surface is subjected to pulsed...

The monograph provides an overview of equipment for processing and processing technology of melons. Until recent years, the primary processing of melons has no industrial production in the CIS countries and abroad. The all-round reduction or complete elimination of the share of manual labor due to the comprehensive mechanization of technological processes is acquiring particular relevance. However, when processing such crops as melons, it is impossible to completely exclude manual labor at the...

The scientific bases of ensuring fire resistance of reinforced concrete and steel building structures in the conditions of modern extreme influences are laid. The current state of fire safety of buildings and structures, as well as approaches, methods and tools for its assessment are analyzed. Analysis of emergencies and fires in the world has shown that the vast majority of them occur in buildings and structures. It is shown that the cause of catastrophic consequences and destruction is the...
